"Silver has rarely been considered as the catalyst for CO oxidation, although it has been recognized to be very active in several partial oxidation reactions such as ethylene epoxidation and formaldehyde synthesis. It is generally believed that a metal support interaction plays an important role in catalytic processes. Therefore in our study, we examined electronic and adsorption properties of cerium deposited onto a polycrystalline silver substrate. Layers of approximately one monolayer of cerium deposited on a clean silver substrate were examined in situ using surface-sensitive techniques - by XPS, ultraviolet photoelectron spectroscopy (UPS) and low energy ion scattering (LEIS). CO molecular adsorption was observed by UPS and LEIS; experimental results exhibited CO adsorption on Ce atoms sites. Oxygen adsorption on deposited layers led to a strong oxidation; stoichiometry of oxidized layers was given by amount of adsorbed oxygen and by temperature.
